I'm in Vail this week and have demo'd the Volkl AC4 and the Rossi Z9. Here are the vitals:
1. 34 y.o 5'10" 195lbs. Been skiing since the age of three. I raced as a teen. I'll ski anything on the mountain from moguls to trees but have a special affinity for long cruisers where I can run imaginary gates at high speed.
2. It snowed for three days straight from the time I arrived. First day of skiing, I skied on 6" of fresh powder, second day 13" of fresh powder. For you math wizards, first day was date of arrival, hence, no skiing.
Onto the boards:
AC4's: 177. Skied these on the 6" powder day. (aside: for you purists, 6" of new snow may not qualify as a "powder day" but it beats ice, icy crud, and bare spots) I skied Gamecreek (Wild Card, Dealer's Choice), the trees in the back bowls (Seldom & Never), some cruisers in Northwoods, and a bomber down Simba at days end for kicks. They were competent in the new powder. They had some float to them, but not enough to qualify them as a good alternative to powder skis. On the groomers, they turned reasonably well, but not enough to make me confident to dig in hard and make consistent GS style turns. They ran well at high speed, but their luke warm turning abilities bothered me. After reading numerous positive reviews of the AC4's, I expected a lot more than what I experienced. Had they been really good in the powder, I would have forgiven their so-so turning performance. They seemed OK at a few things, but not great at any one thing.
Z9: 176. I skied them on the 13" powder day. (Argue with me on 13" qualifying as a powder day and I will show you a glass half empty.) This days travels took me to Game Creek (Faro), Sun Down (Seldom & Never, again), Tea Cup (Emperor's Choice & Genghis Khan), Blue Sky (Champagne Glade & In The Wuides), and a few trips under Chair 2 with the wife. The Z9's tended to s(t)ink in the heavy/deep stuff. It took quite a bit of work to keep the tips up and to make skis work with me on quick turns in the trees (Faro, Seldom & Champagne Glade). In the wide open spaces (Genghis & Emperor's) they performed better as my turns were not as quick. Once in a rhythm, they did pretty well. Later in the day, as all the freshies disappeared and the chop appeared in strentgh, these skis found their calling. The Z9's ran through, around, over, and under the chop with incredible ease. It was as though I was on a completely different pair of skis than what I had dealt with in the early morning. What a pleasure! Genghis, wide open and choppy, was a blast to shred at high speed, making super g turns. Then, when the cats had finished doing some late morning grooming, I ran down Pickeroon and Avanti at high speed making quick turns. The response from the skis was excellent.
Results thus far: AC4, didn't want more. Z9, pretty fine. Hoping to try out some Hot Rods tomorrow.
